鉴于采用了1990年国际温标（ITS-90），它定义了国际摄氏温度，t90，声速在纯水中的温度依赖性进行了研究。利用Del Grosso和马德尔先前发表的实验数据[J. Acoust.美国社会52，1442-1446（1972）]，发现与先前的t68标度的变化是显著的。在100 ℃时，两个刻度（t68-t90）之间的差异为0.026 ℃，导致声速的差异为0.022 m/s。将声速拟合为适用于t90范围0-100 ℃的新的五阶多项式。
In view of the adoption of the International Temperature Scale of 1990 (ITS-90), which defines the International Celsius Temperatures, t90, the dependence on temperature of the speed of sound in pure water is examined. Drawing on the experimental data published previously by Del Grosso and Mader [J. Acoust. Soc. Am. 52, 1442-1446 (1972)], it is found that the change from the previous t68 scale is significant. At 100-degrees-C, the difference between the two scales (t68-t90) is 0.026-degrees-C, resulting in a difference of 0.022 m/s for the speed of sound. The speed of sound is fitted to a new fifth-order polynomial applicable over the t90 range 0-100-degrees-C.
